Overview

ElizaLab

The ElizaLab module has definitions of classes and methods used in the projects for Chapter 10 of Explorations in Computing. The methods and classes in this module are a Ruby implementation of Joseph Weizenbaum’s ELIZA program. Users can “chat” with the Doctor script, which mimics a Rogerian psychiatrist, and experiment by adding new rules to Doctor or writing their own scripts.

Most methods used to install a script or carry on a conversation are in a module named Eliza.

To interact with Eliza, call one of the class methods, e.g. to load the “doctor” script that comes with the ElizaLab module call Eliza.load(:doctor) and to start a conversation call Eliza.run. See the documentation for the Eliza module for a complete list of these top level methods.
